[vz-users] USB IR on Synology NAS

[volkszaehler at vpathuis.dds.nl]

Hi,

Thank you for your suggestion! However, the device doesn't respond the 
first time, directly after creating it (with 300 baud) and writing the 
first command (scrypt attached, as txt for security).
The problem that is described is related to changing the baudrate. So I 
don't think this is the problem ....

Gr,
Vincent
